Reliability

Protects condenser against corrosion from air, water and other corrosive.

Has higher cooling capacity hence better heat transfer.

The outdoor unit is layered with multiple protection coatings to withstand salty air and rain exposure.

Contact sections on Printed Circuit Board (PCB) are resin-potted to prevent adverse effects when in contact with water droplets.

The air conditioner's main mission is to provide a level of durability that allows it to operate stably for years. In order to achieve this, we conduct an accelerated test for 10,000 hours of continuous operation. The results of this test, which is conducted under conditions that are much more severe than actual operating conditions, prove the rugged strength of Panasonic air conditioners.

After the continuous operation test, we remove the compressor from a selected outdoor unit, disassemble it, then examine the internal mechanisms and parts for possible failure and durability. These tests are conducted to see if there is sufficient lubrication inside the compressor under various operating conditions.

The outdoor unit, which is subject to rain and wind, is provided with IPX4 waterproof compliance. Potential problems are checked by tests such as showering the unit for a predetermined amount of time. Contact sections on printed circuit boards are also resin-potted to prevent adverse effects caused by an unlikely exposure to droplets of water.

During distribution, products may be subjected to extended warehouse storage under unfavourable conditions. To simulate these conditions, we place a weight equal to a stack of five product packages on top of the test package, and leave it in that condition in a room at a temperature of 27°C and a humidity level of 85%. After undergoing this simulation test, the product is checked for proper operation.*
* Test methods vary depending on the model.

Even with the large impacts that may occur due to improper handling during transportation, the product packaging has been strengthened to prevent it from being damaged. In addition to conventional vertical dropping, more severe conditions in which the sides, edges, or corners hit the ground first are tested to ensure that the product's rigidity and shock-absorbing materials prevent damage.

The operating noise of the indoor and outdoor units is measured in a high-performance anechoic chamber. The noise test verifies that the operating noise is low enough to allow the user to talk and sleep comfortably while the product is operating.

An actual air conditioner is operated in a test room that simulates a standard living room. Conditions such as the amount of sunlight entering the room from outdoors are changed while measuring a variety of parameters, such as cooling speed, cooling efficiency, and temperature and humidity differences throughout the room. This makes it possible to confirm whether the air conditioner is operating at its optimum performance level under ever-changing conditions.

This test determines whether electromagnetic waves emitted during operation are sufficiently low to prevent interference with other appliances, and satisfy the EMC compliance standards in each country.

Panasonic pursues optimal usability for the remote control because it is an item that is used every day. A variety of tests are conducted to judge the visibility of the button colours, operating ease, and other factors. Also, since the remote control is easily dropped during ordinary use, it is subjected to a 1.5-metre dropping test. This checks that it will not malfunction even when dropped from various angles.

Panasonic air conditioners comply with all necessary leading industrial standards and regulations required for the market in each country. We also conduct a variety of tests to examine the quality of materials used in the parts to maintain high reliability for our products. These tests and industrial standards together with our own internal standards, which are even more severe, make Panasonic air conditioners more reliable.

All parts and materials comply with RoHS/REACH, Europe's world-leading environmental regulations. Stringent inspections of more than 100 types of materials are conducted to ensure that no hazardous substances are included during parts development and production.

Panasonic has set up “eco ideas” factories around the globe. While developing and manufacturing energy-saving products using original environmental technologies, these factories reduce CO2 emissions from manufacturing processes and conduct regional-based environmental communication activities to contribute to both the global environment and the local communities in which they serve.
